Retired Lincoln Lab AI researcher Terry Gleason will talk about his passion, bicycling, as part of his presentation. Bicycling on the area’s rail trails wasn’t always possible; abandoned railroad beds sat dormant until the State and local communities converted them into walking and biking trails. Gleason will describe the peak of railroad activity in the region, its decline, and the conversion of the abandoned lines into rail trails. His story features interesting twists and turns, with Bedford’s own rail trail history exemplifying those surprising changes.
